Every Monday night in the northern Italian town that had perhaps the highest coronavirus death rate in all of Europe, a psychologist specializing in post-traumatic stress leads group therapy sessions in the local church. “She has treated survivors of war,” the Rev. Matteo Cella, the parish priest of the town, Nembro, in Bergamo province, said of the psychologist. “She says the dynamic is the same.”

First the virus exploded in Bergamo. Then came the shell shock. The province that first gave the West a preview of the horrors to come — oxygen-starved grandparents, teeming hospitals and convoys of coffins rolling down sealed-off streets — now serves as a disturbing postcard from the post-traumatic aftermath.
